HOOD FOR BUFFINGr-WI-IEELS.

Specification of Letters Patent.

Patented Mar. 13, 1917.

Application filed. April 21,1916. Serial No. 92,785.

To all whom it may concern.

Be it known that we, WILLIAM M. HAUSER and JAMns McDANIE citizens of theUnited States, residing at Evansville, in the county of Vanderburg andState of Indiana, have invented certain new and useful Improvements inHoods for Buffing-lVheels, of which the following is a specification.

Our invention relates to hoods for buffing or grinding wheels.

The object of our invention is to produce a hood of the characterdescribed adapted to partially surround a buffing or grinding wheel ofordinary construction and recover the particles of metal that are cutfrom the article ground upon the wheel. A further object of ourinvention is to produce a hood adapted to protect the operator from theflying particles and to draw such particles away from the operator andto deposit same in a receptacle in which same may be convenientlyremoved. A further object thereof is to produce an article of thecharacter described adapted to be conveniently adjusted to accommodatethe character and size of the article to be ground. A still furtherobject thereof is to produce a hood and suction device adapted todeflect particles produced from the grinding wheel from the face of theoperator and deposit same in a receptacle from which they may beremoved: and a still further object of our invention is to produce amore-simple, cheap and efficient hood of the character described thanhas heretofore been attained.

To these ends our invention includes the combination and arrangement ofcomponent parts to be hereinafter described and more particularlypointed out in the claim.

On the accompanying drawings, in which like reference charactersindicate similar parts:

Figure 1 is a side view of our invention.

Fig. 2 is a vertical sectional view.

Fig. 3 is a front view, and

Fig. 4 is a back View.

Referring to said drawings, 1 indicates a grinding wheel of ordinaryconstruction and 2 designates a hood adapted to surround the majorportion of the wheel, leaving a minor portion thereof 3 exposed to theoperator. As shown in the drawings, the rear face of said hood is closedwhile the front thereof is entirely open to permit access to the exposedportion of the perimeter of the grmding wheel. Said hood may be ad ustedto 1 containing the particles produced from the grinding operation.

Intermediate of said chamber and recep tacle and the hood proper thesuction pipe 14 communicates with the draw pipe 11 at right anglesthereto at its upper wall, although as shown in the drawings, the lowercontacting walls form an acute angle at 15 which is also somewhat offsetfrom the vertical line of the draw pipe 11.

A suitable suction wheel, not shown in the drawings,,is provided for thesuction pipe 14, whereby a constant flow of air is produced from theopening in the face of the hood through the suction pipe 14, whichsuction draws the particles produced on the grinding wheel inwardly anddownwardly toward the suction pipe 14 and awayfrom the face of theoperator. It will be further obvious that a partial vacuum will occur inthe chamber 12 beneath the right angular connection between the-drawpipe 11 and the suction pipe 14 and thatin making the turn from the drawpipe into the suction pipe the particles produced by the grinding orloufling wheel are likely to fall into chamber 12 I rather than be drawnat right angles into the suction pipe 14.

The receptacle 13 is adapted to be supplied with water for the purposeof retaining said particles and may be removed from the chamber torecover the particles deposited therein.

From the foregoing description and by reference to the accompanyingdrawings it will be appreciated that the hood of our invention may beconveniently adjusted to accommodate same to the nature, character andsize of the article to be treated on the grinding or buffing wheel, andthat the particles produced by the operation may be retained andrecovered in the receptacle 13 through the partial vacuum created in thechamber 12 and the diminution of the force of the suction from the pipe14 at the right angular turnformed with the draw pipe 11.

' draw pipe connected with said hood sections 15' beneath the wheel, avacuum chamber at the base of said draw pipe, a suction pipe c011-nected with said draw pipe intermediate of said hood and vacuum chamberat right angles to the draw pipe, and a removable receptacle carried insaid vacuum chamber for the reception of particles produced bygrinding,substantially as described.

In testimony whereof we hereby aflix our signatures in the presence oftwo witnesses.
